Cropping Problem....PLEASE HELP

I am using a dinasour 300D for my photography right now until I can upgrade. I have a problem that I hope someone will help me with.

This past Sunday, I shot some photos in jpeg/fine. I have done no type of cropping to the images as they are straight from the camera. Now when I set my crop presets in CS2 for a 16x20 print size, I am having a problem with sizing the image so it will not cut off either the top or the bottom. I cannot get it to crop into a 16x20 from the full image. I am also having this problem on some 5x7 crops as well.

Is there a special way of doing this with standard print sizes or am I just SOL. Any help on this matter would be appreciated because it is driving me crazy. PLEASE someone help me. Thank you.

The image ratio on your camera is 3:2 so any other ratio will mean that some of your image will be lost unless you skew the image (not recommended). The 16x20 that you reference has a ratio of 4:5, 5x7 is, well, 5x7.

It may be possible to add a little at the top or the bottom if the background is simple enough. I have done this with great success in the right circumstance.

I usually start off by resizing the image so that the short side is equal to the short measured side of the finished print. Set your crop rectangle to equal your print measure. Move the rectangle around until the framing is the way you like it, then crop. Example: if you want an 8x10, enlarge the original short side to 8". The long side will now be 12".

If you do the opposite of above you would set the long side to be 10" then the new short side will be only 6.66". Enlarge the canvas as suggested above by Poloman.

Hope this is not too confusing.

I've been trying the resize/crop in ACR. Seems to work real well.
